概括
设施间的转移可以提供近乎普遍的儿童体外膜氧化 (ECMO) 服务,减少差异. 然而,对于大多数儿童来说,在医院外心脏骤停时及时获得体外心肺复苏 (ECPR) 的机会仍然有限.
科学领域:
- 儿科重症监护医药 儿科重症监护医药
- 地理空间健康分析
- 获得医疗保健和公平的机会.
背景情况:
- 身体外膜氧化 (ECMO) 对于严重心脏/呼吸系统衰竭的儿科生存至关重要,但仅限于专门的中心.
- 现有的地面运输对ECMO服务的访问显示了差异;设施间传输系统在扩大访问中的作用尚不清楚.
- 儿童与医院外心脏骤停 (OHCA) 的体外心肺复苏 (ECPR) 中心的距离尚不清楚.
研究的目的:
- 评估获得儿科ECMO服务的地理空间范围.
- 评估设施间传输系统在扩大ECMO访问方面的潜力.
- 为OHCA确定潜在访问ECPR的儿童的数量.
主要方法:
- 外体生命支持组织 (ELSO) 数据库的地理空间分析.
- 定义ECMO的"间接接入"是生活在距离ECMO中心120英里以内的医院的60分钟车程内.
- 定义ECPR的"潜在访问"是生活在ECPR执行中心的15分钟车程内,根据城市化和儿童机会水平进行分析.
主要成果:
- 72.8%的儿童有直接驾驶访问ECMO;另有22.5%通过设施间传输有间接访问,接近通用访问.
- 设施间转移不成比例地有利于低机会和农村地区的儿童.
- 只有11.5%的儿科患者有可能获得ECPR服务.
结论:
- 设施间转移显著提高了对儿科ECMO的获取,可能减轻现有的差异.
- 儿科OHCA目前获得ECPR服务的机会非常有限,这凸显了及时紧急护理的差距.
- 地理空间分析对于理解和解决医疗保健准入不平等问题在专业儿科干预中至关重要.

Selected Data About Geographic Locations

Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Protein Networks
4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Facilitated Transport
148.1K
The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In facilitated transport, also known as facilitated diffusion, molecules and ions travel across a...

Network Covalent Solids
16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Primary Active Transport
198.5K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Secondary Active Transport
137.9K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...
